Firefox needs plugin/flash upto date.

Please check if all your plugins are up-to-date. To do this, go to the Mozilla Plugin Check site.

Once you're there, the site will check if all your plugins have the latest versions. If you see plugins in the list that have a yellow Update button or a red Update now button, please update these immediately.

To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

This did not solve my problem. The video area on the screen still is blank and does not play. Any other help would be appreciated. Is there an add-on for the NFL videos?

Please create a screenshot of the problem you're seeing by following the guide mentioned at How do I create a screenshot of my problem?.

Once you've done this, attach the saved screenshot file to your forum post by clicking the Browse... button below the Post your reply box. This will help us to visualize the problem.

Please provide the Error message or no

I am attaching two screenshots. NFL video showing the blank video screen is from Firefox. NFL video (2) is the same web page from IE9.

I played around with my add-ons and found that if I disabled Adblock Plus 2.2.1 the videos work.

I had the same problem the only site that would not play videos was vikings.com Figured out finally that it was the donottrack plugin. Disabled it and can now watch the videos on vikings.com.Hope this help it took me months to track it down. Craig

I discovered that do not track was the problem too. Thanks for your reply.
